public class RegularBlockImpl extends SingleSuccessorBlockImpl implements RegularBlock
Implementation of a regular basic block.
  • Field Details

    • contents

      protected final List<Node> contents
      Internal representation of the contents.
  • Constructor Details

    • RegularBlockImpl

      public RegularBlockImpl()
      Initialize an empty basic block to be filled with contents and linked to other basic blocks later.
  • Method Details

    • addNode

      public void addNode(Node t)
      Add a node to the contents of this basic block.
    • addNodes

      public void addNodes(List<? extends Node> ts)
      Add multiple nodes to the contents of this basic block.
    • getNodes

      public List<Node> getNodes()
      Returns the nodes contained within this basic block. The list may be empty.

      The following invariant holds.

       forall n in getNodes() :: n.getBlock() == this

      This implementation returns an non-empty list.

      getNodes in interface Block
      the nodes contained within this basic block
